Abstract

In this work we study the production of K*(4307) in B decays by determining the J/psi pi K-+(0)(0) and J/psi pi K--(+) invariant mass distributions of the processes B+ -> J/psi pi(+)pi K-0(0) and B+ -> J/psi pi(+)pi K--(+) , respectively. Such K-*(4307) has been recently predicted as a three-body state originating from the dynamics involved in the KD (D) over bar* system, with the KD subsystem forming the D-s0*(2317) in isospin 0, and the D (D) over bar* subsystem generating the X(3872) in isospin 0 and the Z(c)(3900) in isospin 1. The hidden charm content of K*(4307) favors its decay to a state like J/psi pi K and the study of B decays with these particles in their final states can constitute a way of finding experimental evidence for such an exotic vector meson, whose width-in spite of its large mass-is still quite narrow (around 18 MeV).
